Li-ion電池充電管理

XT2063是一款對(duì)單節(jié)鋰電池進(jìn)行恒流/恒壓充電的充電管理芯片。內(nèi)部包括基準(zhǔn)，偏置、電壓比較器和溫度檢測(cè)等模塊，采用DC-DC控制模式，頻率為1.5MHz，充電電流由外部電阻設(shè)置，最大可達(dá)2A。\r\n\r\n 當(dāng)輸入電壓低于4.35V時(shí)，芯片進(jìn)入SLEEP MODE工作模式，此時(shí)功耗會(huì)降低到60μA以下，同時(shí)關(guān)斷充電。該芯片充電過(guò)程由涓流、恒流、恒壓和再充電等過(guò)程組成，外部有2個(gè)LED可以對(duì)各種充電狀態(tài)進(jìn)行顯示。\r\n\r\n 內(nèi)置溫度保護(hù)與負(fù)載短路保護(hù)，確保IC的高可靠性。\r\n\r\n 通過(guò)調(diào)節(jié)MODE端口的信號(hào)，可以選擇輸出電流為編程電流或者0.6倍編程電流 ● 恒流PWM電流模DC-DC控制\r\n\r\n● 恒壓LDO控制\r\n\r\n● 防反灌功能\r\n\r\n● 充電電壓精度為±1%，充電電流精度為±10%\r\n\r\n● 低功耗工作\r\n\r\n● 充電狀態(tài)指示標(biāo)志和充滿狀態(tài)指示標(biāo)志\r\n\r\n● 自動(dòng)再充電\r\n\r;
